qiujayen/sticky-layoutmanager works perfectly for my needs.

interface StickyItem {
    boolean isSticky();
}

class FooAdapter extends GroupAdapter implements StickyHeaders {

    // ...

    @Override
    public boolean isStickyHeader(int position) {
        Item item = getItem(position);
        return item instanceof StickyItem && ((StickyItem) item).isSticky();
    }
}

class FooHeaderItem extends Item<FooHeaderItem.Holder> implements StickyItem {

    // ...

    @Override
    public boolean isSticky() {
        return true;
    }
}

RecyclerView.LayoutManager lm = new StickyHeadersLinearLayoutManager<FooAdapter>(ctx);
mRecyclerView.setLayoutManager(lm).

That's fantastic @iPaulPro ! I get asked about this all the time and I've always just said it's not in the scope of this library. A custom layout manager is a great solution.
